Fanout Exchange

多个queue都可以绑定到exchange，并且每个queue都会接受到消息
producer（client.php）


$exchangeName = "exchange_01";
try {
    $connection = new AMQPConnection();
    $connection->setHost('127.0.0.1');
    $connection->setPort(5672);
    $connection->setVhost("/");
    $connection->setLogin('guest');
    $connection->setPassword('guest');
    $isConnect = $connection->connect();
    if (!$isConnect) {
        exit("connect rabbitmq error\n");
    }
} catch (AMQPConnectionException $e) {
    exit("connect rabbitmq error\n");
}
$channel = new AMQPChannel($connection);
try {
    $exchange = new AMQPExchange($channel);
    $exchange->setType(AMQP_EX_TYPE_FANOUT);
    $exchange->setName($exchangeName);
    $exchange->declareExchange();
    for ($i = 0; $i < 5; $i++) {
        $bool = $exchange->publish("hello world ". $i);
        echo $bool . "\n";
    }
    $connection->disconnect();
} catch(Exception $e) {
    exit("rabbitmq error: " . $e->getMessage() . PHP_EOL);
}



consumer（server_1.php）

DIRECT TYPE

direct 有点像一对一处理
